This year, as in years past, I will shop almost exclusively online for holiday gifts. I love the convenience, the fact that I don't have to take along my toddler (except for rides in our swiveling office chair), and the ease of using comparison shopping sites like Froogle to bargain-hunt.

The one thing I despise about shopping online is the shipping fees, and I'm not alone. According to a study conducted by Jupiter Research a few years ago, high shipping fees were the No. 1 reason customers abandoned their online shopping carts. Consumers resent the feeling of being blindsided by excessive shipping charges, often not revealed until the last step of the online shopping process. "There's so much competition for my business," says Jodie Burns of Alexandria, Va. "I don't need to pay outrageous shipping fees when I can just find the item cheaper within a matter of minutes online."

Merchants are standing up and taking notice this year. Many of the big online stores are offering discounted or free shipping deals this season in order to secure your business. But not without strings attached, of course.

Here are a few things to keep in mind when you're searching for a deal on shipping:

1. Take notice of the exclusions. Often "free shipping" deals exclude purchases such as oversized or unusually heavy items, gift certificates, or items for which you are using another promotional code. Some merchants maintain lists of items that are eligible for free shipping, steering you toward higher-priced items, items for which they have excess inventory, or items that net greater profit. Retailers may also require that the entire order ship to the same destination in order to receive the savings.

2. Check the estimated shipping date. Some "free shipping" offers come at the price of speed. For example, indicates that free shipping orders have an estimated shipping time of four to 10 business days, while the standard shipping window is just three to seven business days. Add on time for "order processing," and you may be waiting a while for your merchandise.

3. Be wary of the "minimum purchase" bait. Most merchants simply can't afford to absorb all of the shipping costs for their merchandise, so they compromise by offering free shipping on larger orders. While this makes good business sense, it may also induce you to buy things you don't need simply to qualify for the savings.

Still, if you take a few moments to shop around, you can save big on your holiday orders with free shipping deals. Here are just a few of the online retailers hoping to attract your interest (and your dollars) with deals on shipping this Christmas.
